Ingredients
Scale
Fruit
- 6 large Apples (about 1.4 kg, peeled and grated)
- 2–3 tablespoons Lemon juice (freshly squeezed)
Dry Ingredients
- 4 cups Rolled oats/quick oats/oat flour (360g total; can blend rolled oats to oat flour if needed)
- ¾ cup Granulated sugar (plus 1 tablespoon for topping)
- 1 teaspoon ground cinnamon
Fat
- 2/3 cup Unsalted butter (cold, divided into about 30g for base, 125g for topping)
Instructions
- Preheat & Prepare the Pan: Preheat your oven to 180°C (350°F). Line a 9-inch (23cm) springform pan with parchment paper and set aside.
- Make Oat Flour (if needed): If you don’t have oat flour, place 4 cups (360g) of rolled oats in a blender or food processor and blend until coarse flour forms with some texture remaining. You can also mix rolled oats, quick oats, or oat flour for varied texture.
- Make the Oat Mixture: In a large bowl, stir together the oat flour, granulated sugar, and ground cinnamon to evenly distribute ingredients.
- Grate the Apples: Peel and grate the apples using a box grater. Toss the grated apples with 2-3 tablespoons of freshly squeezed lemon juice to prevent browning and allow them to release some juice; set aside.
- Layer the Cake: Grate about 2 tablespoons (30g) of cold butter into the bottom of the prepared pan. Sprinkle 3–4 tablespoons of the oat mixture over the butter and press gently to form the base layer. Spread one-third of the grated apples, including some juice, over the oats. Repeat these layers two more times (oat mixture then apples), finishing with the remaining oat mixture on top.
- Top with Butter and Sugar: Grate the remaining 125g of cold butter over the top oat mixture evenly. Sprinkle the final tablespoon of sugar on top for a golden, caramelized crust.
- Bake: Place the pan in the preheated oven and bake for 35–45 minutes until the top is golden brown and the apple filling is soft and bubbling.
- Cool & Serve: Allow the cake to cool in the pan for 20 minutes, then release the springform pan. Cool completely before slicing. Serve at room temperature or warm for best flavor.
Notes
- You can use a mixture of rolled oats, quick oats, and oat flour to create a layered texture.
- If you don’t have oat flour, blend rolled oats to a coarse flour consistency.
- The lemon juice helps prevent the apples from browning and adds a subtle tartness.
- This cake is naturally sweetened with granulated sugar, but you can reduce sugar or substitute with alternatives if you prefer.
- Cold butter grated on top creates a lovely crunchy crust after baking.
- Use a springform pan for easy removal and neat slices.
